Title: Signal mixing systems
IPC: H03D7/20
Filed: 1947-03-14
Abstract: 647,526. Valve generating circuits; radio signalling. PHILCO CORPORATION. March 14, 1947, No. 7158. Convention date, March 14, 1946. [Classes 40 (v) and 40 (vi)] [Also in Group XL (a)] In a circuit for mixing a high frequency with a relatively low frequency the two frequencies are caused to vary the velocity of electrons entering a drift space in a velocity modulation valve and the electron flow is substantially reduced or interrupted periodically at the lower frequency. The required output frequency (e.g. the sum or difference frequency) is only present during one part of the lower frequency cycle and by reducing the electron flow during the remaining part of the cycle increased efficiency is obtained. As shown, the velocity modulation valve comprises a first resonator B to which a 3300 Mc/s. local oscillation is applied by loop 15, connected by a drift space 29 to an output resonator C tuned to the required sum (or difference) frequency. The frequency modulated signal from the final I.F. stage 22 of the receiver at a radio relay station (Fig. 1, not shown) is applied to the resonators via transformer 23 to vary the velocity of the electrons arriving at the resonators from the cathode K. The control grid G of the valve G is biassed to cut-off but is supplied with the I.F. voltage through a phaseadjusting network 26, 30, 31 to render the valve conducting during the portion of the I.F. cycle during which a voltage is produced at the frequency of the sum of the local oscillator and I.F. signal. The phase change required is 90 degrees plus that required to compensate for the transit time from the grid. The circuit may be modified by moving switches 17, 18, to the alternative position in which the I.F. signal is applied directly to the control grid to interrupt periodically the electron current. An I.F. voltage is also induced in circuit 25 connected to the cavity structure and detuned to the extent necessary to produce the desired phase shift. The electron stream may alternatively be velocity-modulated by magnetic means or interrupted by magnetic or mechanical means or by deflecting the electron stream, and the power output may be derived through fluorescence, thermal or mechanical effects, or by charging particles on a fixed or moving screen. A magnetic field may also be used to guide the electrons through a curved drift space.

Abstract: 242,149. Breton, J. L. March 20, 1925. Plates, dishes, and the like, washing. - In a machine of the type having a rotary basket in which the plates &c. are arranged like the blades of a turbine, the basket being rotated, first in boiling water to cleanse the plates &c. :and then in air to dry them, a central openinglis provided in the cover of the machine to draw in air which is forced out, by the rotation of the plates &c., through a peripheral nozzle. As shown in Figs. 1 and 2 an inclined, casing 1 supports at its centre a pivot 3 having a ball 4 upon which rests a socket 5 fixed at the centre of the basket 7. A handle 10 is fixed to the socket 5 and the casing is closed by a cover 11 the upper part of which is hinged. A tubular axle 6 fixed to the socket 5 carries radiating spokes supporting the basket 7 and two notched rings between which the plates rest. The casing is partly filled with washing liquid which is picked up by the plates as they rotate and sprayed over the parts of the plates which are not immersed, the vapours being forced out through the nozzle 13. After the washing and rinsing liquids have been drained away through a drain-cock 14 the basket is rotated, for centrifugal draining, and drying by air drawn in through the central apertures 12 in the cover 11 and expelled through the peripheral nozzle 13. The casing may be heated by a gas burner 15. In a modification the basket rotates on a horizontal axis, the cylindrical casings being arranged vertically and comprising two semi-cylindrical parts, the upper part forming the cover, and having an air-inlet aperture near the central axis of the machine and ,a peripheral nozzle. Plates of any size are maintained in the rotary basket between outer notched rings of sheet metal or wire and springs with loops fastened upon the shaft, these springs being spread out to enable the plates to be inserted. Fig. 7 shows this modification adapted for the washing of cups, the basket comprising an outer ring 43 having inwardly-extending racks 42 against which the cups are pressed by springs 44 fixed to the shaft. The basket may be dispensed with, the plate-fasteners being fixed to the casing which is itself mounted on a pivot and receives rotary motion. The draincock 13 comprises a conical shell within which turns an apertured conical plug 35 open at the lower end and kept in place by a screw which also fixes the handle 38.
